Were you using the Chessconnect extension or the Chessnut app?
The creator of the extension mention in the thread here (post #19)
That if you have a problem with the extension and cheat detection to push them further.
@Martin_Stahl needs to clarify what he means, as I have never seen anything about that and these boards are going to explode over the next couple of weeks/months with lots of them coming for Christmas.
(BTW, your account does not look like it is banned, so what exactly happened?)
How many people has this happened to? I've just had my account restricted after using my new chessnut air for the first time last week. I've not had any proper explanation and no response to my message to support (no surprise there really) but just putting two and two together. What an absolute shower.
Also, where are these boards "not currently recommended"? This quote below is from Martin Stahl:
"Not 100% sure about iOS but the Chessnut air boards are not currently recommended for live games if you plan on playing tournaments anytime after using the board.
Currently that can get accounts restricted, though I think Chessnut may be working with the site on ways to be better supported."
